The quality of container bags directly affects subsequent market development, so it is essential to conduct certain quality tests before the product leaves the factory.
There are two effective quality tests used for container bags before leaving the factory.
1. The first is stress testing.
Put the fully loaded container bag on a pressurizing machine for a pressurization test. The pressure applied by the press is four times the full load weight of the container bag. You may use the static load method, that is, the self-weight of the four-layer fully loaded bag. The pressurization time is For more than eight hours, if the contents do not spill out and the bag body is not damaged during this test, it means that the container bag has passed this test.
2. The second is the drop test.
Lift the fully loaded container bag with lifting equipment. The bottom of the bag should be more than 0.8m above the ground, and then drop vertically to a solid and flat ground. If the contents do not overflow and the container bag body is not damaged, it means Pass this experiment.
